Division Spotlight
Nuclear Criticality Safety
NCSD provides communication among nuclear criticality safety professionals through the development of standards, the evolution of training methods and materials, the presentation of technical data and procedures, and the creation of specialty publications. In these ways, the division furthers the exchange of technical information on nuclear criticality safety with the ultimate goal of promoting the safe handling of fissionable materials outside reactors.

Commercial nuclear innovation "new space" age
In early 2006, a start-up company launched a small rocket from a tiny island in the Pacific. It exploded, showering the island with debris. A year later, a second launch attempt sent a rocket to space but failed to make orbit, burning up in the atmosphere. Another year brought a third attempt—and a third failure. The following month, in September 2008, the company used the last of its funds to launch a fourth rocket. It reached orbit, making history as the first privately funded liquid-fueled rocket to do so.

This paper describes the design, construction, and test of a setup able to make thermal neutron irradiation at grazing angles of incidence on a sample lying inside an isotropic high neutron flux. Such characteristics are deemed to be very interesting for the future research facilities that will provide intense neutron beams. Indeed, collimated beams can be found easily in neutron sources around the globe, but the new equipment enables use of a relatively intense flux that will allow fast testing of materials. The aim of this study is the understanding of the mechanical stability of structural materials used for the manufacturing of neutron guides such as borosilicate glasses. This new equipment proved the unstability of some of these glasses to thermal neutron irradiation when exposed above a given fluence.
